Reflex arcs in which the sensory stimulus and the motor response occur on the same side of the body are:
(a) Contralateral
(b) Paraesthetic
c) Ipsilateral
(d) Monosynaptic.

A reflex arc is the neural pathway that controls a reflex action, involving a sensory receptor, sensory neuron, integration center, motor neuron, and effector. It enables rapid, automatic responses to stimuli without conscious brain involvement.

An ipsilateral reflex occurs when the sensory input and motor output happen on the same side of the body. This means the stimulus and response are localized to one side, such as the knee-jerk reflex.

A contralateral reflex involves a sensory stimulus on one side of the body and a motor response on the opposite side. This type of reflex helps coordinate actions between both sides, like the crossed extensor reflex.
